DPR'EIENT IN' CARRIAGE-COUPLING.

Be it known that I, LEWIS GRIM, of Fort Branch, Gibson county, Indiana,have invented certain new and useful Improvements in Carriage-Couplings;vand I hereby declare -the following to be a full, clear, and exactdescription thereof; reference being had to the accompanying drawings,making part of this specification.

This invention relates to a novel method of attaching the front axletothe bed or bodyof acariiage; and

The. improvement consists in constructing the coup- .ling in such amanner as to permit of the carriage-body maintaining a horizontalposition, no matter how much said axle may be inclined.l In theaccompanying drawings FigureI 1 is a perspective View of acarriage-coupling embodying my improvements, and

Figure 2 is a vertical section of the same in the plane of the aX-le.

IA represents the front axle of a carriage, and 4this axle is, at itsmid-length, united to the customary axlebed B, by means of a clip, C,whose upper end is provided with a circular recess, c, which is adaptedto receive the collar or boss d of the king-bolt D.

The upper end of the king-bolt terminates in a he'ad, E, which is hingedto the metallic portion, F, of the head-block, by means of the pintle orpivot e.

The-metallic portion, F, Vof the head-block has fitted withinit a woodenportion, G, into which the perch H ismortised, and to which the spring Iis attached by the bolts J J K is a bolt, which passes throughtheiwooden portion G of the head-block, and also through the tenon h oftheperch, and this bolt may project a sucient distance above the springto receive one end of a stay or brace-bar, whose other end may besecured to the perch 4at any convenient place.

Whenever it is desired to construct the carriage with side-braces, theirfront ends may be mortised into the wooden portion G of the head-block;A

The collar d, which rotates within the recess c of the clip, notonlyperforms the duty of a filth-Wheel, but it also receives all of thestrain which the king'bolt is usually subjected to, andtherebyeiieetually prevents the bending or breaking of the latter memberof th'e coupling. l

In case either end of the axle A should be elevated, tlie carriage-bodyis not tilted, as the king-bolt D merely turns upon its hingedconnection e, and allows the carriage no maintain its horizontalposition, as clearly shown in fig. 2.

' It'swill be seen that the operative parts of my coupling are few andsimple in their construction, and that they can be readily ap'plied toany carriage or springz wagon.

I claim herein as new, and of Vmy invention- A carriage-coupling,consisting of the clip O c, kingbolt D d E, hinged connection e,combined metallic and wooden head-block F G, and attaching-devicesJ J',or their mechanical equivalents, for the purpose herein describedand setforth.I

In testimony of which invention, I hereunto set my hand. l v
